WK1 Troubleshooting / Problems Discussion / Dealer ServiceIf you are having some problems with your Jeep Grand Cherokee SRT8 and need assistance in troubleshooting and diagnosing the problem, this is the proper place to discuss it. Were you treated fairly or poorly at a dealer? Warranty issues? Let us know.

My check engine light has been on for the last two days....I got the light to go away by clearing the computer with the battery dis-connect method but it came back on. I took it to auto-zone so they could hook up the diagnostic computer and it was throwing the code P2096. What does that mean? My Jeep is stock. I have no idea what it could be, but I did just get my transmission replaced from the dealer if that matters. I just want to know if it is something I can fix myself because the dealer is an hour away from me.

Set Condition:
If the PCM multiplies short term compensation by long term adaptive as well as a purge fuel multiplier and the result is below a certain value for a calibrated amount of time over two trips, a freeze frame is stored, the MIL illuminates and a trouble code is stored. Two Trip Fault. Three good trips to turn off the MIL.

Since you said new trans, i would get under there and check all the wires from the O2s and make sure they didnt pinch or forget to reconnect anything.

Thanks robpp! Here is what I was thinking....I bet they had to unbolt the exhaust to replace the tranny and when they re-installed it, they didnt line it up correctly. I am saying this because I just noticed an interesting rattle coming from my exhaust which sounds like an exhaust leak to me....I'll check it out today.

I did figure out the problem...... I was under the jeep checking all of the exhaust connections when one of my o2 sensors was extremely loose! This was definatley the problem. It looked like they had just put it in place and forgot to tighten it because all the other ones were fine. Air was definately getting in there and I could wiggle it with the lightest touch. Also, they cut the factory tie strap that held the o2 sensor wire up high and away from the heat of the pipes and didn't put a new one on! I could see the old tie strap that had been cut still on there. The wire was just dangling there about half an inch above the pipe, I was surprised it hadn't melted yet. That is some real heat-resistant rubber insulation they have over those wires! So I used my own tie strap and cleaned up the wiring. Also the dealer forgot to tighten the bolts all the way where the stock muffler hooks up to the flanges. After all this, I went over everything under the jeep around the transmission with a fine tooth comb. Other than what's mentioned above, everything else was fine under the jeep and looked good. I have since then reset the CEL and it has not come back on and the exhaust leak noise has disappeared. I'll tell you what though, mechanics at dealers need to slooooow down and quit doing everything so rushed!
